Causes

Cancer occurs when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This is called a growth or tumor. The term cancer refers to malignant tumors. They can invade nearby tissue and spread to other parts of the body.

Mesothelioma is type of cancer is almost always caused by exposure to asbestos. It is a fibrous mineral that is used to be present in many construction materials and car parts. Even a small amount of exposure can be a risk. Other fibers can cause mesothelioma.

Symptoms

This cancer can take up to 20-40 years to develop. Early signs of pleural mesothelioma include:

Pain or trouble breathing

Long-lasting cough

Pain under the rib cage or in the abdomen

Weight loss, sweats, and fatigue

Symptoms may not start until a long time after the tumor develops.

Diagnosis

You will be asked about your symptoms and medical history. A physical exam will be done. You may be referred to a doctor who specializes in lung problems or cancer. A pulmonologist focuses on the lungs. An oncologist focuses on cancer.

Sometimes, it is hard to tell the difference between this and other, more common types of
lung cancer.

These same tests and others may also be used to find out if cancer has spread outside the pleura. It is important to know whether and how far the cancer has spread in order to plan treatment. This step is called the staging process. It helps determine the level of treatment.
